WRENCH.

To all whom it may concern:

Be it known that I, LUKE S. SLOANE, a citizen of the United States, residing at Okmulgee, in the county of Okmulgee and State of Oklahoma, have invented new and useful Improvements in Trenches, of which the following is a specification.

My present invention has reference to wrenches.

My ,object is to produce a pipe wrench which may be quickly adjusted to engage an object between the jaws thereof and which shall be of such construction that a binding between the jaws of the wrench and the object acted upon will not occur when the wrench is turned to take a fresh hold on the object.

The foregoing, and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this specification.

In the drawings Figure 1 is a perspective view of a wrench in accordance with this invention.

Figure 2 is a sectional view on the line 2-2 of Figure 1'.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Figure at is a sectional view on the line H of Figure 1.

As disclosed by the drawings, my improved wrench comprises essentially two members, each of which having a shank, one of the shanks is indicated by the numeral 1 and the other by the numeral 2. The shanks, are arranged one over the other, and have their confronting edges toothed, as at 3 and 4: respectively. The teeth 3 shank 1 are designed to be received between the teeth 4: of the shank 2. The shank 2 is of a materially greater length than the shank 1 and has one of its ends provided with a handle 5 and its other end with a head 6. One end of the shank 1 is provided with an angle head 7 which is disposed opposite the head 6. The inner face of the head 7 is straight, but is toothed or serrated to provide a gripping jaw S. The outer face of the head 6 is disposed at an angle as indicated by the numeral 9. The angle end 7, of the head 6, is, at a distance below the portion thereof formed with the shank centrally provided-with a depression form- Spccification of Letters Patent.

ing a pocketlO, the said pocket having its side walls provided with inwardly directed ribs 11 and its rear wall '12 arranged at the same inclination as the face or end 9. The head 6, adjacent to the outer end thereof is provided with threaded opening 13, which enters from its rear and communicates with the pocket 10. In this threaded opening there is a set screw 14 that has the end thereof that enters the pocket of a conical formation, as indicated by the numeral 15.

Arranged for slidable movement over the angle face 9 of the head 6 is a toothed. or serrated jaw 16. The jaw is centrally provided on its inner face with a web flange 17, whose sides are provided with longitudinal depressions 18 to receive the ribs in the pocket. The inner end of the web rests against the inner angle wall 12 of the pocket, and the upper wall of the pocket has a depression 19 therein which forms a seat for a comparatively light helical spring-20 that exerts a pressure against the upper end of the web of the j'aw16. The web of the jaw 16 has its lower or inner face cut away from the end thereof, the upper wall formed by the said cut-away portion forming a rounded shoulder 21 that is engaged by the conical end 15 of the screw 1 1. The spring 20 forces the movable jaw 16 outwardly of the head 6 and into contact with the set screw. When the wrench is arranged to receive an object between the jaws thereof the jaw 16 will be moved inwardly against the pressure of its spring which is especially true when pressure is applied on the handle of the wrench to turn the object. When such pressure is released, the spring will be free to exert its pressure against the jaw 16 to force the same outwardly of the head 6, and consequently prevent binding on the object by the heads. Thus the wrench may easi y ratchet over the object engaged.

On the edges of the shank 2, directly inward of the head 6 thereof there are spaced cars 22 which contact. with the sides of the shank 1. Also on the shank 1 there is a substantially iJ-shaped stirrup member 23. The member 23 is preferably removably secured to the. shank 2, by the means 2 1. The side members of the yoke project a. suitable distance beyond the outer edge of the shank 1. and have pivoted therebetween, as at 25 a lever 26. The lever, opposite its pivot has a cam projection 27 whereby, when the lever is swung to one position, to bear on the outer edge of the shank 1, and move the said shank bodily to bring the teeth 3 thereof into engagement between the teeth A} of the shank 2. 'Thus the sections comprising the wrench mag be easily and quickly adjusted.

aving described the invention, I claim':-- In a Wrench construction, as herein described, co-operating heads having angle shanks disposed in lapping relation and having their confronting faces for the major length thereof provided with coengaging teeth, ears on the sides of one of the shanks adjacent to the head thereof frictionally engaging the sides of the other shank but not projecting therebeyond, a yoke surrounding the first mentioned shank, secured thereto and having its parallel arms arranged against the sides of the secondshank and projecting therebeyond, and a cam lever pivoted between said arms at the outer ends thereof for engagement with the outer surface of the second mentioned shank.

In testimony whereof I afiix my signature.
